Effect of ischemic preconditioning on alteration of myocardial cell membrane permeability of felines during cardiopulmonary bypass;

Results The solubility,stability in gastrointestinal tract,membrane permeability and presystemic metabolism of drugs were the major factors on oral drug absorption.

The involvement of oxidization of peroxid in the antigen-antibody reaction makes the cell membrane permeability enhanced, so the fluorescence-labeled antibody stain can infiltrate into the cell easily and contact the antigen rapidly and diffusely, and then the antigen-antibody crosslinking can be formed efficiently.

Biopartitioning chromatography(BPC) emulates drug-membrane interactions by introducing biomembrane-mimetic into chromatographic system,and has become a high throughput screening platform for evaluating drug membrane permeability and biological activity.

coli membrane permeability,and membrane potential.

The various death signals induce di-rectly and indirectly(through Bcl-2family proteins)the increase of mitochondrial membrane permeability,the release of cytochrome c and the activation of caspases.

Treatment of peritoneal dialysis-related peritonitis previously focused mainly on the choice of antibiotics,but now it is recognized that the overall strategy of its prevention and treatment should start from the beginning of the peritoneal dialysis catheter insertion.
